最短路径在Arcgis空间分析中的实现

Realization of the Shortest Path Based on Space Analysis in Arcgis

针对公路修建规划过程中如何选址的问题,提出了一种结合地理信息系统技术的选址模型,该模型是利用Arcgis中的Spatial Analyst模块,数据基础是研究区的DEM数据,通过对河流、坡度、起伏度这三种地形影响因子进行综合处理后,实现了最短路径的选择,并结合Arcgis中的三维分析扩展模块3D Analyst实现了最短路径在三维地形中的可视化,从而为用户提供一个更加直观的可视化环境.

According to the problem of site selection during highway constraction and design, the authors presented a site selection model which combines with geographic information system technology. The model is to use Spatial Analyst module in Arcgis, and the data is based on the study area DEM data, achieving the choice of the shortest path through integrated dealing with the three affecting factors of terrain, such as rivers, slope, undulating, and combining with extension model of 3D Analyst in Arcgis to show the shortest path in three-dimensional terrain. Also, it shows a better real visual world for users.
